I have to agree with everyone here! So many annuals, so little room! :o)
I never was big on marigolds because they dont SMELL great (ie cut flower) but had them around my tomatoes last year and they won me over with their constant blooms and always looked great! This year I bought a couple different ones to try: a Starlet (red) and vanilla (white)
Grew Bright Lights cosmos last year and think I'm going to stick with those shorter version vs. the sensation mix (mine grew 6-7 feet tall). My FIL always grew portaluca and those are on my "start indoors" list
Nigella, Calendula, and Larkspur are on my list for this year as well.
ZM i read your post at work and missed the paragraph on razzle dazzle gaillardias. Looks like I was right on in my observation
